ROLLER-SKATE.

SPECIFICATIQN forming part of Letters Patent No. 329,913, dated November 10, 1885. Application filed October 11, 1884. Serial No. 145,298. (ModeL) To all whom it may concern.-

Be it known that I, BENNETT KINDBLADE, a citizen of the United States, and a resident of Batavia, in the county of Kane and State of Illinois, have invented new and useful Improvements in Roller-Skates, of which the following is a specification, reference being had to the accompanying drawings, illustrating the invention, in which- Figure l is a sectional elevation of a rollerskate embodying my improvement; Fig. 2, an inverted view of the skate with one truck removed; Fig. 3, a top view of Fig. 2; Fig. 4, a top view of one of the trucks removed from the boot-support; Fig. 5, a perspective view of the pivot-plate, on which the track is centered, removed.

The nature of the present invention consists in the novel means for adjusting the boot-plate to fit different-sized boots, novel construction and adaptation of double springs to prevent 10st motionin the movement of the truck, and the novel construction of truck-hangers, whereby the wear of the connections is on pivots which relieve the peripheries of the attaching-screws from wear, as the whole is hereinafter fully described and shown.

K K represent the two-part boot-plate of the skate, K being the heel. D D represent brackets attached, respectively, to the under sides of the plates K K by means of rivets in a substantial manner. Tapped through these brackets is a right-and-lel't screw-rod, O, to which is affixed a burr, P, for turning the screw-rod so as to bring the brackets to or from each other and shorten or lengthen the two-part plate K K. Riveted to the under side of plate K is a plate, L, which is provided with an open slot, f, vertically through its opposite end, that the plate may have a guide astride of a screw-bolt, M, put through the plate K,where the adjustment is made.

That the plateL mayhavea suitable lateral support,the plate K is formed with side ears, M M, and riveted to these ears at their under sides is a plate, N, which is countersunk on its top side to receive the said plate L.

The brackets D D are vertically slotted to receive the connected ends of forked springs O 0, whose free ends pass astride of lugs Q Q on the truck-disks I 1. Both parts of each double spring, being sprung half of the thickness of the lugs outward, are in tension where the wheel-axles are at right angles to the center line of the boot-plate; consequently there is no 10st motion as there is where only one spring to a truck be employed. This is important, enabling the skater always to be sure of the position of the trucks. To insure strength with lightness of metal,the brackets D D, by solid castings E, are connected with upper disks, H H, and brackets F F, the brackets being attached to the boot-plates by rivets in the ordinary manner.

The disk-platesH H I I are constructed on the ordinary inclines outward and downward, to give a lateral incline to the boot-plate K K but thetruck-frames I I are so constructed that the axle-trees B B lie vertically under the center of motion of the disks H I, in contradistinction to the ordinary methods of placing the axle-trees on lines at right angles to the faces of the disks. By this means the trucks are farther apart, and in turning a corner the wheels are not brought so close to the boot-plate, thereby contributing largely to the ease of motion and safety of the skates.

The disks H I are provided with a recess, a b, in which is placed an annular pivot-plate, c. The disks being in position, as shown at Fig. l, with the pivot between them, are held in position to turn by means of ascrew, G, put through the disk I and pivot center-plate c, and tapped into the disk H, the head of the screw bearing against an ordinary washer, J. This construction is such that the only function of the screw G is to hold the disks face to face, the wear coming on the pivotplate 0, which may be replaced where worn so as to give any lost motion.

ment of the axle-trees.

It is proper to state that the skate shown is designed to supply the demand for perfection in action and elegance; but the truck attachments may be used in connection with wooden boot-supports, and serve a like purpose to that herein set forth.

Those portions shown but not described are well-known constructions, needing no explanation.
